  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

homebuilt motion control camera

This is fantastic! I've actually been bugging an engineering student at UVA for the last few weeks on initiating this kind of study. I'll gladly bring a Red down to Blacksburg for some tests when I get mine- but don't hold your breath, I'm at the back of the line. Anyway, I'm in Charlottesville so if there's any way I can help at least we're close.
 
Filmfan222 I'm interested too!!

btw I came across this discussion on net
http://www.cinematography.net/Pages DW/MotionControlDesign.htm

best part is:
Industrial Light and Magic had a team of software designers working over a year trying to develop their own Apple based program. After a reputed 1 million dollars was spent on the own in-house motion control system they pulled the plug and bought a Kuper system for (then) $3,500.00 US.

I was thinking about for Stop Motion programs like mine might be useful since when you use the curve fitting you can move the source points around so they are closer at the ends of the moves, and after curve fitting you will get a smooth transision of the line segment length, that when the frames are shot will look like acceleration and deceleration.

If you oversample during stop motion then use my Fuse command in my Edit list you can murge the frames to look like motion blur, maybe a 128x oversample would work well? Over sample would also give a clean mate for blue/green screen and when you fuse the frames (after doing the composite with the plate) you get great motion blur!

With my system you might be able to sync several computers to get any number of axis by using the aux relay out to un-pause the next computer in a chain or something like that, or just use the xtals for what they do... if you need help you know where to look...

You know where to find my programs, others are like here,

Anyway, you get the idea, ask for more info at CAD_CAM_EDM_DRO on yahoo groups, there is also info to be found on google groups...

You can build a 5A stepper driver for maybe $30 from parts? So free software plus maybe $50 per axis for a motor and driver? look for motors on ebay, junk yards, and so on... There is some info on my site about how to figure out the wires on random stepper motors...

>>Note, Some tasks or programs used require Windows ME (tm) or Windows XP Home SP3 (tm) with the FreeDOS FAT32 (tm) disk mounted as a slave drive. Things may work better if all disks are formatted FAT32, which should work up to 2TB per disk.<<
 
Really interested to see what you worked on, but it appears you have taken down the .mov files. I toyed with the idea of doing something like this back in film school, but was flamed for even suggesting such a "ludicrous" idea. :) Right. I would have tried to pull it off if I had a bit more background and some financing to embark on it. Glad you did. Please repost the files.

Best.
 
It's on our website. I don't want to hijack this thread so in keeping with the DIY nature of the topic I can say that you can make a reasonable motion control rig by using a few geared motors with pulleys. Like others have said though, the most import part of moco is stability... from which comes repeatability.
 
used or new KUPER 2001, OR RTMC48 board

used or new KUPER 2001, OR RTMC48 board

Hey guys,

I am trying to locate a used preffered or new kuper board. I have old kuper rtm16 and it wont do what i need. I am looking for Kuper2001, or the older Kuper RTMC48. I will also try and buy the jogbox as well.

Thanks
